Some Aspects Of Regeneration Silviculture In Spruce-Aspen Stands In Alberta, L. A. Smithers

Aspen Bibliography

Surveys of spruce-aspen stands in Northern Alberta have shown that natural regeneration of white spruce is generally a failure on areas which have been logged but not burned (Candy 1951).

Field Guide To Aid In Recognition Of Natural Triploid Aspen, Philip N. Joranson, Dean W. Einspahr, J P. Van Buijtenen

Aspen Bibliography

Swedish experience with the genetic improvement of the European aspen (Populus tremula L.), a species which is closely kin to our North American quaking aspen (P. tremuloides Michx.), suggests that the rate of volume increment and the length of fiber tracheids might both be increased in North American aspen by finding or producing trees which possess a triple set, rather than the usual double set, of "chromosomes". Chromosomes (Figure 1) are found within and inner region--the nucleus--of each of the millions of cells formed during the growth of a tree.

Aspen Defiberization And Refining Of Product, Robert Craig Jr.

Aspen Bibliography

Because of the great demand for wood fiber and because there is an abundance of aspen available¹/ for this purpose, its conversion into a usable fiberized material offers possibilities. It also affords an outlet for low-quality bolts developed in any aspen logging operation or from land of poor quality.

Aspen Properties And Uses, Zigmond A. Zasada

Aspen Bibliography

Because of the large demand for lumber during the last 10 years, and particularly during the war period, aspen has entered many new fields of use. At present there is widespread interest in the possibilities of building new industries and extending the life of old ones by increased use of aspen. Many people are interested in becoming familiar with this wood. This report has been prepared to give general information on the properties and present uses of aspen and also to help in correcting some of the existing erroneous ideas about this wood.

Seeding Grass On Deteriorated Aspen Range, A. Perry Plummer, George Stewart

Aspen Bibliography

The herbaceous undercover on much of the aspen range in the Intermountain region is badly deteriorated. These areas, naturally highly productive, when revegetated can contribute greatly towards a much needed supply of range forage. One of the major obstacles to successful seeding has been the difficulty of getting the seeds covered with soil since both standing and fallen trees interfere with the use of drills, harrows, or other machinery. In the search for methods to overcome this difficulty, it was found that for open aspen stands the covering of seeds is unnecessary when the right precautions are taken in other …

How To Reseed Utah Range Lands, A. Perry Plummer, Richard M. Hurd, C. Kenneth Pearse

Aspen Bibliography

Additional low cost forage is urgently needed by Utah's range livestock industry. Seeding of depleted tracts in accordance with recently developed methods and principles will help supply this forage and is entirely feasible. Where the value of the increased forage will repay the cost of planting, careful reseeding of selected sites is fully justified.

The important part that reseeding can play in restoring ranges to their former capacity has been demonstrated. Although satisfactory results can be obtained on many sites during average or better years, much more study is needed to insure consistent success in abnormal years and to extend …

Weather And Plant-Development Data As Determinants Of Grazing Periods On Mountain Range, David F. Costello, Raymond Price

Aspen Bibliography

Fundamental in economical range-resource management is the determination of proper grazing periods. It is of prime importance to be able to establish a date in the spring when the range has produced sufficient feed to keep livestock in thrifty condition, when it is reasonably safe from excessive trampling and packing of the soil, and when the more important key forage plants have attained sufficient development to withstand grazing use. Such opening dates, as well as the time to defer and rotate grazing and to remove livestock from the range, are dependent in part on the prevailing weather conditions and on …

The Pine Tipmoth In The Nebraska National Forest, M. H. Swenk

Nebraska Agricultural Experiment Station: Historical Research Bulletins

On May 8, 1911, Mr. Smith Riley, the District Forester, with headquarters at Denver, in a letter to Acting Supervisor Pierce at Halsey, requested that the Nebraska Agricultural Experiment Station take up energetically the investigation of the pine tipmoth in the Nebraska National Forest. This request being presented to the Department by Mr. Pierce later in the month resulted in the presentation of the problem to the Experiment Station Council as a proposed Station project. The project was approved on May 31, 1911, and the expenses of the investigations of 1911 and 1912 that are reported upon in this bulletin …

Grazing Periods And Forage Production On The National Forests, Arthur W. Sampson, Harry E. Malmsten

Aspen Bibliography

Stockmen in the West have always had confidence in the adequacy of the native forage crop to provide pasturage for their livestock. Indeed, under normal climatic conditions this enormous natural resource has not failed the grazier, except where it has been called upon to meet unreasonable demands. The productivity of the range has declined sharply, however, wherever the requirements of plant growth have been disregarded for many years in succession. Where there has been too early or too frequent and to heavy grazing, undue trampling, or some other unsatisfactory feature of range use, the results have been uniformly bad. Many …

Climate And Plant Growth In Certain Vegetative Associations, Arthur W. Sampson

Aspen Bibliography

The relation of climate to the growth and development of vegetation is of profound importance in both practical and experimental agriculture. It is extremely useful to know the cause of successful growth and establishment, or of partial success or failure, of various species in different plant associations and under widely contrasted climatic conditions. The climatic requirements of various plant types are largely responsible for the results obtained in the case of experimental seedings and plantings of most species. Once the adverse climatic factors are definitely known, failures with plants may be largely avoided by the judicious selection of sites or …
